IMPROVEMENT IN HUB-CAPS FOR CA RRIAGES.

Specification forming part of Letters Patent No. 181,541, dated August29, 1876; application filed August 5, 1876.

To all whom it may concern: Be it known that 1, JOHN H. SANDERSON,

of Greenfield, in the county of Franklin and cheap and simple method ofsecuring hub-caps in place, which will admit of their being distantlyremoved and replaced, and which will overcome the usual difficulty oftheir being rattled loose by the vibration of the wheels. This end Iaccomplish by providing the hubband at its outer end with a narrowinternal flange, and then providing the hub-cap on its inner face withan annular flange of the proper diameter to enter within the flange ofthe cap, and with yielding arms or protuberances, which, being crowdedwithin the flange of the band by the act of pressing the cap to itsplace, hold the latter from falling out, while, at the same time, theypermit its removal by the application of a moderate force.

Figure 1 represents a central sectional view of the hub-band, and a sideview of the cap in position to be applied thereto; Fig. 2, a centralsectional View of the band and cap united; Fig. 3, an inside face viewof the cap provided with the flange and spring-arms, as in the precedingfigures; Fig. 4, a central sectional view, showing a cap of modifiedform applied to the hub-band.

A represents the hub-band, provided at its outer end with an internalannular flange, a. B represents the hub-cap, provided. on its inner sideor face with an annular flange, b, adapted to fit snugly within theflange a or the band. C represents the yielding projections, adaptedtoeng-age over the inside of the band-flange a, and retain the cap inplace.

These yielding projections may consist of spring-arms secured to theinside of the cap, and extending out through notches in its flange, asshown in Figs. 1, 2, and 3 or they may be protuberances, formed on theflange by indenting the same'from the inside, as shown in Fig. 4 or theymay be spring-arms, formed by cutting slits in the flange b and bendingthe intermediate portion of the flange outward. In either case, however,their action and purpose will be the same--that is to say, as the cap ispressed home they will yield and pass inside of the flange a of theband, and then spring outward inside of the same, and thereby retain thecap tightly and securely in place, as represented in Figs. 2 and 4,while, at the same time, they allow it to be removed by the applicationof a moderate force outward under its edge.

Having thus described my invention, what I claim is p The combination ofan internally-flanged hub-band, A, and a flanged cap, B, provided withyielding arms or protuberances G, substantially as shown and described.
